Why the MTAP2 does not measure the insulation of the motors
a high voltage DC is aplied to measure the insulation, if motor is on and you apply the voltage to the test, there is a short circuit. Mtap is used for online motors.
Great Question Oscar. The MTAP 2 uses an isolation transformer which prevents a ground wall induced drop in system line voltage from being seen on the secondary of the MTAP2 isolation transformer. Insulation integrity is best checked on a de-energized motor with a DC test voltage like that provided by the MCE®.
